COLLAPSITBLE METAL IEOLE.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed April 4, 1914. Serial No. 829,516.

To all whom it may concern Be it known that 1, Oscar: VALENNE, a subjectof the King of Belgium, and a res1- dent of New York, county and Stateof New York, have invented a certain new and useful Improvement inCollapsible Metal Poles, of which the frllowing is a full, clear, andexact specification. V

This invention relates to a class of poles adapted to be used forsuspending wires, electric lamps, and the like therefrom.

My invention has for its object primarily to provide a collapsible poledesigned to be employed for supporting telegraph CI trolley wires,electric lamps, and the like by making the pole of metal in a formwhereby it will effectually withstand the force of high winds and stormyweather, and which is made in separate parts in a manner whereby a largenumber of the poles may be manufactured in entirety and subsequentlyassembled without the use of connecting bolts,

thereby dispensing with the requirement for skilled workmanship in theerection of the poles. This is ilCCflllPllSllQtl mainly by providingthree substantially \l-shaped members,(tr standards which are disposedin spaced relation in the formation of a triangle so as to convergeupwardly toward each other, and these standards are connected by anumber of detachable spaced metal retaining elements, or-straps whichserve to prevent the standards from accidental displacement when thepole is assembled as well as permitting the parts of the pole to bereadily discrnnected when it is desired to remove the pole, or when oneor more parts thereof are to be replaced by others in event of beingdamaged. 1

A further object of the invention is to provide a collapsible pole ofsimple and oilicient construction, and which is susceptible of beingmade in various sizes so as to combine great strength and durability.

With these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawingswhich forma part of this specification, and will then be pointed out 1nthe claim as the end of the description.

In the drawings, Figure 1 is an elevation, partly broken away, of oneform of metal pole embodying my invention when used for supportingwires. Fig. 2 is an ele vation of a form of the pole when used forsupporting trolley wires, electric lamps, or

the like. Fig. 3 is an enlarged top plan, partly in section, of one ofthe triangular metal straps used in coniunction with the pole. Fig. 4 isan enlarged perspective view, partly in section, of one of the cornersof the strap shown in Fig. 3. Fig. 5 is an enlarged perspective viewshowing the underside of the cap employed in the pole. Fig. 6 is anenlarged top plan of the cap. Fig. 7 is an enlarged fragmentary view,partly in section, showing ('ne of the standards of the pole embedded inthe ground when erected, and Fig. 8 is an enlarged view taken on theline II-II of Fig. 2.

The collapsible metal pole has three members, or standards 10, 11, 12which are alike in formation, and all of the standards are preferablysubstantially V-shaped, as viewed in cross section. lhe standards 10,11, 12 are made of steel, or other suitable metal, .and these standardsmay be of any desired length, width, or thickness, as cccasion requires.When the pole is erected the standards 10, 11, 12 are disposed in spacedrelation in the form of a triangle so that the upper parts thereof willconverge toward each other, as illustrated, and the lower end of each ofthe standards is bifurcated to provide two diverging prongs, as 13 and14.

To erect the pole the lower end portions of the standards 10, ll, 12 areembedded into a block of cement, as 15, after being properly disposed intriangular arrangement, and the block of cement as well as contiguousparts of the standards are then sunken in the ground, as 16, to asuitable depth. Previously to erecting the pole in this manner, andafter the standards 10, 11, 12 are triangularly arranged with relationto each other, the standards are detachably connected by a number ofretaining elements, or straps, as 17, all of which are similarly formed,excepting that all of the straps vary somewhat in size. The straps 17are madeof steel or other desired metal, and each strap is triangular insha 2e to conform to the formation of the standard when arranged, asexplained. Each of the straps 17 has three enlarged corresponding cornerportions l8, 19, 20 all of which are substantially the shapes of darts,as viewed transversely, and each corner portion has an approximatelyfiat longitudinally disposed body, as 21. On the outer converging edgesof the body 21 of the enlarged corner of each strap is a verticallydisposed substantially mitting the straps to be removed therefrom whenit is desired to disassemble the polefor the purpose of removing it,or'for replacing parts thereof in event of being damaged. Thedart-shaped corner portions 18,

w 19, of each of the straps are connected by cross-bars 21-, 25, 26which are preferably T-shaped, as viewed in cross-section, and

, these bars are integrally formed with the corner portions so that thepole may be made in a comparatively limited number of interchangeableparts to permitthe pole to be transported in sections and readilyassemled when being erected. To connect the standards 10, l1, 12 bymeans of'the retaining elements, or straps '17 after the standcards aretriangularly arranged, as above referred to, the largest strap is guidedover the standards so ascto be' disposed on the lower parts thereof. Theother straps are then similarly applied on the standards in spacedrelation in the order of their sizes so that the smallest strap will beat the top part of the standards, and on the top of the standards is aremovable metal cap, as '27. -The cap 2? is substantially triangular inshape, and in the underside ofthe cap adjacent to its corners areapproximately V-. shaped recesses 28, 29, 30. The recesses 28, 29, 30'are slightly larger than the standards to allow the upper end of eachstandard to be disposed in one of the recesses, and, through thecenterof the cap is an opening 31 to permit a bracket, as 32 Fig. 1, tobe applied to the pole Whenthe pole is usedfor supporting electric wiresfor telegraphing'or other purposes on the upper-part of, the pole arefastened one or a number of brackets, as 33, on which may be mounted asuitable numberof cross- 'bars,-as 3-l Fig. 1, and these cross-bars as owell as the bracket 32 serve to permit the Copies of this patent may beobtained for five. cents each, by addressing Washington. D. C.' I

electric wires to be connected to thepole by the'usual, or any preferredmeans. 'When the pole. isemployed for supporting trolley wires, as 35,or electric lamps, as 36, and the like, a form of bracket, as indicatedat 37,

may be mounted on the upper part of the pole. By constructing thecollapsible pole with the forms. of the spaced 'V-shaped standards,together with the forms of the straps, as herein described, it isobvious that these parts may be made in comparatively limited sizes, ifdesired, but will tend to combine sufiicient strength and durabilityfor. being capable of withstanding high winds and stormyweather, and bymaking the pole in the separate interfitting parts it may be readilyassembled and erected with.

out-the use of bolts, or other connecting means. i

In the foregoing description, I have embodied the preferred form of myinvention, but I do not wish to be understoodas limit- 7 ing myselfthereto, as I am aware that modifications maybe made therein withoutde-- parting from the, principle, orsacrificing any of the advantages ofthis invention,

therefore I res'erveto-myself the right to make such changes as fairlyfall within the" scope of the appended clain Having thus described myinvention, I

claim as new and desire to secure'by Letters Patent A collapsible polecomprising three pole sectionsof acute angle formationfin'cross section,the lower ends thereof being adapted to be anchored in the ground,pole-section binders disposed at intervals along the length of the pole,each binder comprising 7 three dart-shaped corner portions and eachna'lly'disposedcbody and a vertical flange at the outer converging edgesthereof, said' flange having vertical passages therethrough cornerportion comprising a fiat longitudi frictionally receivingthepolesections and integrally formed T-shaped cross-bars connectmg thecorner-portions, and a cap for the upper ends of the sections.
